Saṃyukta Āgama (368)

原文：如是我闻。一时。佛住舍卫国祇树给孤独园。尔时。世尊告诸比丘。当修无量三摩提。专精系念。修无量三摩提。专精系念已。如是如实显现。云何如实显现。谓老死如实显现。乃至行如实显现。此诸法无常。有为有漏。如是如实显现。佛说此经已。诸比丘闻佛所说。欢喜奉行。 

Explanation: The World-Honored One told the bhikṣus: You should cultivate immeasurable meditative concentration (samādhi), and within samādhi single-mindedly and diligently sustain mindfulness of the twelve links of dependent origination. Only after diligently sustaining mindfulness of the twelve links of dependent origination within immeasurable samādhi can the meaning of the Dharma manifest in the mind as it truly is. How does it manifest as it truly is? The dharma of aging-and-death manifests in the mind as it truly is: the phenomenon of aging-and-death, the cause of aging-and-death, the condition of aging-and-death, how aging-and-death arises, how aging-and-death ceases, and the Noble Eightfold Path cultivated to extinguish aging-and-death—all manifest as they truly are, and the mind becomes utterly clear. And so on down to birth, becoming, grasping, craving, feeling, contact, the six sense bases (ṣaḍāyatana), name-and-form, the six consciousnesses, and volitional formations—each of these dharmas manifests in the mind in turn: the phenomena of these dharmas, the causes and conditions that produce them, how they arise, how they cease, and the Noble Eightfold Path cultivated to extinguish them—all manifest in the mind as they truly are. These dharmas are all impermanent; they are all conditioned and tainted dharmas. If this principle can manifest in the mind in such a true manner, the great wisdom of liberation will be attained. 

"As it truly is" means the inherent state of the dharma, its real state unknown to people—not the surface phenomena commonly known to all, but that which is subject to arising and ceasing, change, impermanence, suffering, emptiness, and non-self. When the mind can manifest the dharma in this way, wisdom arises in an instant, and the mind abides in the realm of liberation.
